Brandon Sanderson is an American writer recognized for his contributions to the fantasy and science fiction genres.

Beyond the Cosmere, Sanderson has authored other notable series. These include the humorous children's fantasy adventure line, Alcatraz; the young adult science fiction series, Cytoverse; and a young adult superhero adventure series known as The Reckoners. He also penned the science fiction novellas in the Legion series, which follow Stephen Leeds as he tackles mystery cases using his unique mental abilities. Additionally, Sanderson was entrusted with continuing Robert Jordan's renowned fantasy series, The Wheel of Time, following Jordan's passing.

A defining characteristic of Brandon Sanderson's work is the Cosmere, an expansive, shared universe encompassing many of his fantasy novels. Set across diverse planets, these stories maintain a subtle interconnectedness. Characters may traverse between worlds, and events in one series can have faint echoes or direct implications in another, creating a rich, layered reading experience for dedicated fans. This ambitious world-building allows for a grand narrative scope that unfolds gradually across multiple distinct book series and standalone novels within the same fictional cosmology.
